This standard specifies the headspace-gas chromatography/mass spectrometry for determination of such solvent residuals on papers for cigarette as benzene, toluene, ethylbenzene, xylene, styrene, methanol, ethanol, isopropanol, n-propanol, n-butanol, acetone, 4-methyl-2-pentanone, butanone, cyclohexanone, ethyl acetate, n-propyl acetate, n-butyl acetate, isopropyl acetate, 2-ethoxyethyl acetate, 1-methoxyl-2-propanol, 1-ethoxy-2-propanol, 2-ethoxyethanol, dimethyl succinate, dimethyl glutarate, dimethyl adipate; other solvent residuals may also use this method for reference.
This standard is applicable to wrapping paper of cigarette carton and case, cigarette tipping paper and cigarette lining paper; other cigarette papers may also use this standard for reference.
2 Principle
When the solvent residuals in samples reach a balance between gas phase and matrix (liquid phase or solid phase) in sealed container at certain temperature, gas phase part is brought into gas chromatography-mass spectrometer to subject to separation and identification; after matrix correction, determine the solvent residuals in samples.
